SPOP-IN-6b dihydrochloride is a potent speckle-type POZ protein (SPOP) inhibitor with an IC50 of 3.58 μM.In Vitro: SPOP-IN-6b dihydrochloride shows IC50s of 2-10.2 μM for A498, Caki-2, Ketr-3, 769-P, 0S-RC-2, and 786-0 cells.
SPOP-IN-6b (0.1-3.0 μM; 10 hours) dihydrochloride can suppress SPOP activity, and then increase suppression cancer substrate protein PTEN and DUSP7 content.In Vivo: SPOP-IN-6b (40-80 mg/kg; intraperitoneal injection; daily; for 25 days; nude mice) dihydrochloride can slow down the growth of tumour by suppressing SPOP.
